Perpetrators' Pre-offence Behaviour in Cases of Post-separation Intimate Partner Homicide: Risk Indicators and Precursors of Homicidal Offending

• In Event: Homicide and violent crime: Risk factors and weapon use

Abstract

Separation conflicts and post-separation periods are known to be high-risk times for intimate partner homicide (IPH). In a file-based study in Germany (files originating from years 2012-2020 from public prosecutor’s offices in the states of Baden-Wuerttemberg and North Rhine-Westphalia), the emergence of attempted and completed homicides was analysed with a particular focus on the later perpetrator and his pre-homicide behaviour. Based on the file data, the relevance of the history of violence in the pre-separation relationship, the significance the later perpetrator's behaviours related to the separation process, especially suicide threats or attempted suicides, the role of threats and intimidation, of stalking behaviour and of planning and preparatory actions for the homicide are analysed. Results point to windows of opportunity for recognising and responding to increased risks of impending post-separation IPH. In many cases, IPH after a separation has a significant history and does not arise more or less spontaneously from an escalating situational conflict. This results in intervention and prevention options for the (ex-)couple's private social network, for authorities and support organisations concerned with the (ex-) couple / family and - at least in case of previous relevant incidents and interventions - also for the police. The results are discussed with regard to corresponding awareness-raising and training needs among relevant professional groups and organisations.
